[Dynamics of fluid volumes of body sectors in patients after laparoscopic surgery]. / Dinamika ob"emov zhidkostnykh sektorov organizma u bol'nykh, perenesshikh laparoskopicheskie operatsii.

An investigation of the state of volumes of the organism's fluid sectors (general, extra- and intracellular fluid) by a noninvasive method of double-frequency impedancemetry has revealed the influence of preoperative preparing the patients and restriction of the water regimen after operation upon the development of moderate dehydration of the extracellular sector. During the operation lasting about an hour the intravenous administration of 400 ml of crystalloid solutions maintains the volumes of fluid sectors within the due values. These solutions injected in greater volumes result in accumulation of the extra- and intracellular fluid. The antiperistaltic purgation of the intestine before the operation reduces the concentration of calcium in blood by 1 mmol/l at an average.

[Method of increasing the effectiveness of assisted circulation]. / Sposob povysheniia éffektivnosti vspomogatel'nogo krovoobrashcheniia.

The effect of venoaortal and atrioaortal auxiliary circulation (AC) on myocardial contractility of the left and right ventricles was examined in patients with acute heart failure following cardiac surgery. The atrioaortal AC technique proved to be more effective. A short-time warming of the blood from 37 degrees to 39 degrees C enhances the favourable effect of auxiliary circulation on myocardial contractility.
